Hello,
the script reload mechanism relies on a counter (version number) stored
in shared memory. It is set to 0 when kamailio start and increased with
each RPC reload command.
Each worker process has a copy of the value in a local variable.
More details:
The script is reloaded only if the process calls the function apy_reload_script().
There are processes which are not SIP workers ranks: 0, -1, -2, -4.
SIP workers have ranks: 1, 2
It would appear that the RPC server is in -2: I can see it reload the script in itself:
it calls apy_reload_script() which calls apy_load_script()/apy_init_script()
However I don't see worker -2 instruct workers 1,2 to run apy_load_script().
What I need is a mechanism to schedule a function call in the workers: something like
// pseudo-code
for (i = 1, i < 3; i++)
// run_in_worker(int rank, void* function)
run_in_worker(1, apy_reload_script);
